Description
The correct length of the Error Message Register (EMR) in Arria® 10 devices is 78-bits. This register stores the Configuration RAM (CRAM) error location that is induced by a Single Event Upset (SEU) event.
Due to an issue in the Quartus® Prime software, the following IPs incorrectly indicate that the EMR data width is 119-bits for Arria 10 devices.
Altera® Error Message Register Unloader IP
Advanced SEU Altera Advanced SEU Detection IP
Altera Fault Injection IP
Resolution
You may tie EMR[118:78] to GND in your design in these IP. The EMR data width in these IP will be updated to 78-bits in a future release of the Quartus Prime software.
